That he probably had just learned about in school, and got in trouble for it.
Background: We sometimes meet friends of ours for good, cheap Italian food at a place in our town called the “Silverball Pinball Museum.” (The owner is a New Jersey Italian, so his grandmother would spin in her grave if his restaurant’s Italian cooking was sub-par). Our friends brought their 11-year-old grandson and one of his pals, who caused a bit of a stir with the management. The boy had pockets full of fake $100 bills that had a little Chinese writing in one corner. He went up to the second-floor balcony and began throwing the bills down into the crowded room of pinball players. (Helicopter Ben Bernanke probably did the same thing as a lad, and may be still doing it in “retirement”). The manager was all in a huff over it, talking about “breaking the law,” etc. I just said to him the kid was just practicing monetary policy, everyone laughed, and the cops were not called.
